Measuring NH3 emissions using acid traps

In the last few days two papers have been published that fit together very nicely and have given us deeper insights into the dynamics of soil carbon after organic matter inputs differing in qualtiy and quantity. Christopher Poeplau first author of one paper and involved in the other paper.
